Title: Improvements in or connected with receivers of high frequency sound waves
IPC: G01H11/08
Filed: 1920-02-25
Abstract: 139,496. Pupin, M. I. Feb. 4, 1918, [Convention date]. Piezo-electric instruments.-In apparatus for receiving high-frequency sound waves for signalling, a crystal detector is used in which changes of electric potential are produced by changes of pressure (piezo-electric effect). and arrangement is made whereby a difference in phase between electric impulses due to the received sounds is utilized to make the apparatus selectively responsive, to the particular frequency required. Frequencies of the order of 100,000 per second are mentioned, so that the apparatus is not appreciably affected by waves of lower frequency, e.g. of the order 3000 per second. Each detector consists of a plate of quartz 1, 4 cut parallel to the optical axis. and having sheets of metal foil 2, 3, 5, 6, secured to its opposite faces. The sheets 2, 5 which face the oncoming sound are connected together, and the sheets 3, 6 are connected respectively to the grid and filament of a thermionic amplifier. The plates 2, 4 are displaced relatively in the direction of the sound propagation a distance equal to an odd multiple of a half wave-length of the desired frequency so that the potential variations are in opposite phase. As the detectors are, in effect, connected in opposition, the resultant impulse is the sum of the effects in the two detectors. With long waves, the potential variations in the two detectors are nearly in phase, and the resultant impulses are negligible. The impulses are taken to amplifying or detecting devices through circuit 10 inductively coupled through a transformer 9 with the plate circuit of the amplifier as shown. A single crystal detector is non-selective, responding to sound waves of all' frequencies.

Abstract: 392,694. Imitation fires ; electric stoves. ROSS, F. A., 23, The Broadway, Tynemouth, North Shields. March 1, 1932, No. 6126. [Classes 39 (iii) and 126.] An apparatus for producing imitation flame effects comprises a moving member b-illuminated by a luminous element c, and a reflecting member or members a in which moving images of the member b, or of an image formed in it of the luminous element, appear. In the apparatus shown in Figs. 1 and 3 the moving element comprises a twisted strip b of polished metal mounted vertically in bearings and rotated by a fan at the upper end of the spindle which is subjected to the air currents rising from a coloured lamp or luminous heating element c. Moving images are thus produced in the curved reflector a. Further reflectors a<1> are shown, in the form of perforated and corrugated pillars of U section, through which the images in the rear reflector a may appear in order to give the effect of flames passing up the pillars. Further moving members b may be provided, and the member b may have other positions, such as at b<1>. In a modification, the moving member is formed of spiral strips surrounding the luminous element. Fig 6 shows in plan another form of the apparatus in which the moving member comprises a number of parabolic reflectors b which rotate about the central vertical axis and reflect moving images of fixed luminous elements c into corrugated strip reflectors a. A heating element may be provided in the centre to rotate a hot air fan driving the reflectors b. Alternatively, the elements c may be rotated with the reflectors b by a motor or mechanical means. In a further form shown in Fig. 7 a bowl reflector a contains a moving member b formed of reflecting strips rotated about the heating element c by a fan d operated by the air stream passing through a tube n in the base of the bowl. Rods or tubes, indented, corrugated, or perforated, or refracting members, such as prisms or beads of quartz or glass, may be used for the moving members, and mechanical driving means may be employed instead of the hot air fans. The luminous elements may consist of gas or electric heating elements, or a separate luminous source may be used.

[Also in Division H4] A display device comprises a plurality of luminescent semi-conductor diodes 4 disposed along the length of an elongated crystal 1 of semi-conductor material having electrodes 2 at each end, means for applying a voltage to the electrodes to produce a high field domain near one electrode and maintain the domain as it propagates to the other electrode and means for deriving a voltage pulse from the domain which pulse travels with the domain and causes the diodes to luminesce. Indium electrodes 2 are attached to the ends of a CdS piezo-electric crystal 1 supporting luminescent GaP diodes with the P-regions uppermost and interconnected to earth by a wire 5 via a leak resistance 6. Synchronizing pulses and a video signal comprising transmitted data are separated, the pulses trigger a pulse generator whose output is applied between electrodes 2 and the video signal is passed to an amplifier and delay circuit before being applied to the wire 5. The pulses are propagated along the crystal and at each diode combine with the video signal to produce luminescence proportional to the combined signal. In a second embodiment diodes are disposed between two parallel CdS crystals. The diodes are formed by depositing Cu 2 S on one crystal, gold electrodes and resistance layers are disposed between the Cu 2 S and the other crystal. The synchronizing signal is applied across both crystals with a delay between them to produce voltage pulses causing current to flow through each diode in succession. The current is varied by an electric field produced by applying the video signal across the pair of electrodes at one end of the crystals. The device is used in T.V. and facsimile systems. Two dimensional images may be formed on a plurality of devices.
